Which if any of the accessories for my Nikon D90 are likely to work with a d800?
In particular, I have a Nikon MC-DC2 cable release and a Opteka right angle viewer. I expect I will be using a cable release with the d800 fairly often, and those listed for it at the NikonUSA site are all pretty expensive. Of course, the prices are small compared to the investment in a camera and lens, so I will pay what I have to, if necessary. It just goes against the grain to spend so much on a cable release.
I do occasionally use the right angle viewer with my Nikon D90, but it may not actually be necessary for what I would do with the d800. Using the rear screen with a loupe may suffice.
